The Denyen is purported to be one of the groups constituting the Sea Peoples.
They are mentioned in the Amarna letters from the 14th century BC as possibly being related to the "Land of the Danuna" near Ugarit.
The Egyptians described them as Sea Peoples.
The Denyen have been identified with the people of Adana, in Cilicia who existed in late Hittite Empire times. They are also believed to have settled in Cyprus. A Hittite report speaks of a Muksus, who also appears in an eighth-century bilingual inscription from Karatepe stele in Cilicia. The kings of Adana are traced from the "house of Mopsos," given in hieroglyphic Luwian as Moxos and in Phoenician as Mopsos, in the form mps. They were called the Dananiyim. The area also reports a Mopsukrene (Mopsus' fountain in Greek) and a Mopsuhestia (Mopsus' hearth in Greek), also in Cilicia.
They were raiders associated with the Eastern Mediterranean Dark Ages who attacked Egypt in 1207 BC in alliance with the Libyans and other Sea Peoples, as well as during the reign of Rameses III. The 20th Egyptian Dynasty allowed them to settle in Canaan, which was largely controlled by the Sea Peoples into the 11th century BC.
These areas also show evidence of close ties with the Aegean as a result of the Late Helladic IIIC 1b pottery found in these areas. Some scholars argue for a connection with the Greek Danaoi (Δαναοί)—alternate names for the Achaeans familiar from Homer. Greek myth refers to Danaos who with his daughters came from Egypt and settled in Argos. Through Danaë's son, Perseus, the Danaans are said to have built Mycenae.
